CSCS has recently upgraded its Cray XK6 platform to Cray XK7 by introducing NVIDIA K20x devices together with CUDA 5, and a new Cray programming environment that includes OpenACC compilers. The goal of this 2-day training course is to introduce new features of the platform and its programming environment, and to provide hands-on training on CUDA5 and OpenACC programming. Course attendees are also encouraged to bring their own codes.
